core: fix a few small memory leaks on exit (#6470)

* renderer: add destructor and destroy event source

add destructor and destroy the event source.
one less leak on exit of compositor reported by asan.

* compositor: cleanup eventloop on exit

destruct hyprctl to release the event sources, and properly cleanup the
event loop on exit of compositor. less leaks on exit reported by asan

* threadmgr: destroy event source on destruction

destroy the event source on destruction.

* eventloopmgr: reset eventloopmgr on exit aswell

reset the eventloopmanager on exit of compositor and free the leaking
last idle frame on monitor destroy.
